|Water Cooler/Low Temperature Stiming Reaction Bath – DHJF Series Ultra (-100℃、-120℃)
|Traditionally, when cooling temperature is below -100℃, it is achieved by combining three compressors together to form a three-leveled refrigerating group, which is complex , costly and accompanied by risk of leakage.
While, our R&D department designed a new powerful single-stage compression condensing refrigeration heat exchanger. DHJF Series Ultra Low Temperature Stirring Reaction Bath was developed on the base of this technology. This internal heat exchanger is composed of outer evaporating tubes and several inner condensing tubes. Compared with the three-leveled refrigerating group, the single compressor refrigeration unit is simpler, safer, more stable and more cost-saving.
